Rocket Men
The Rocket Men were a group of pirates who plundered planets for their riches. Their name was a reference to their use of jetpacks. (AUDIO: The Rocket Men, AUDIO: Return of the Rocket Men)
At some point the Rocket Men, led by Van Cleef, encountered Steven Taylor, but he was saved by his future self, who was apparently shot dead. (AUDIO: Return of the Rocket Men)
The Rocket men, led by Ashman, invaded Platform Five, but were defeated by the First Doctor, Ian Chesterton, Barbara Wright and Vicki Pallister. During this time Ashman was killed. (AUDIO: The Rocket Men) Following Ashman's death, more than a dozen groups of his fellow Rocket Men began fighting for control of his territories. (AUDIO: Return of the Rocket Men)
The Rocket Men's king, Shandar later joined forces with the Master. (AUDIO: Requiem for the Rocket Men)
The Rocket Men eventually became a much weaker force. To make ends meet they stole whatever ship they could get their hands on, and used it to transport grain across the galaxy. (AUDIO: The Two Masters)
